Docker 安装 mysql8方法介绍

一、下载mysql8镜像
docker pull mysql

二、创建mysql8配置文件

vi /etc/my.cnf //编辑MySQL配置文件

my.cnf文件内容

[mysqld]
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
datadir = /var/lib/mysql
secure-file-priv= NULL
// Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
// Custom config should go here
!includedir /etc/mysql/conf.d/

三、创建mysql容器

docker run -p 60306:3306 -e MYSQL_ROOT_PASSWORD=123 -v /etc/my.cnf:/etc/mysql/my.cnf:rw -v /etc/localtime:/etc/localtime:ro --name mysql8 --restart=always -dit mysql
-p 60306:3306 //本机60306端口映射到容器3306端口
-e MYSQL_ROOT_PASSWORD=123 //设置MySQL的root用户密码
-v /etc/my.cnf:/etc/mysql/my.cnf:rw //本机的MySQL配置文件映射到容器的MySQL配置文件
-v /etc/localtime:/etc/localtime:ro //本机时间与数据库时间同步
–name mysql8 //设置容器别名
–restart=always //当重启Docker时会自动启动该容器
-dit mysql //后台运行并可控制台接入

四、进入mysql控制台修改密码

docker exec -it b6cfb244d0c0 bash //进入MySQL容器
mysql -uroot -p123 //进入MySQL控制台
ALTER USER ‘root’@’%’ IDENTIFIED WITH mysql_native_password BY ‘123456’; //修改root用户密码
